Gmail Notifier & MS Messenger

[sam9]

Unable to logon to Gmail Notifier or MS Messenger using
iMAC Intel. Was able to use it fine until the upgrades.

Using the Gmail Notifier for MAC, at the Sign-in Box, after inserting the user id or password:

SIGN-IN FAILED


Using the MS Messgener(forced to use the latest version 6.0.2), after inserting the ID and PSWD, the error message Box says:

Either date and time settings are incorrect or the digital
certificate file is not valid or installed on your computer. If the date and time are correct, see your network administrator to verify that your digital certificate file is valid and installed.

I had this problem for a while now and was lucky to find ADIUM software which is really great, but I wish to know how I can resolve this problem and why this has happened.

Thanks in adavnce
